What July feels like
July is when the marine layer usually gives up by mid-morning and the beach towns fill. Comic-Con takes over downtown for a week and hotel prices go strange; plan around it or lean into it.
Rain is genuinely rare — most years, July stays dry start to finish. There’s a little humidity in the air, but nothing that changes your plans.
Can you swim?
The ocean runs about 67° — brisk but swimmable.
